31 Claims.

In the preparation of salmon for canning successive individual fish are disposed upon a feed table back first, heads all directed to the same side, and extending transversely of the direction of feed, and, so disposed, each is advanced therealong in close succession and at a fairly rapid rate of advance by a positive drive means synchronized with abeheading knife which beheads the fish as it passes the beheading point. Be fore beheading each is pulled towards its head end to align the pectoral girdle with the beheading point. Each beheaded fish is promptly dropped belly-up into a trough, which guides it for tailward movement, and delivers it, tail first, to a fish cleaning machine with which the feed table and beheading knife are synchronized, of which the best known type i that sold under the trade-mark Iron Chink. Therein it is engaged and picked up first by its tail and then along its back, to lie circumferentially disposed upon a rotative upright bull ring, and as it advances the fins are removed, it is slit open, and the entrails are cleaned out. It must be accurately and properly held to the bull ring, belly outermost and tail foremost, as it moves circumferentially with the bull ring. To do this it is pinned at spaced points along its back by positioning pins in groups which are long enough to receive and hold as large a fish as is ordinarily expected to be cleaned. These groups of positioning pins are intended to engage each successive fish at a particular point in relation to its tail, and unless the fish is thus accurately positioned, or unless all the positioning pins engage it truly and accurately, trouble is likely to result. The fish may be damaged and its monetary value lost, or the entire machinery may become jammed, or the cleaning may not be properly performed and the pack might be downgraded.

While the upright bull ring is accurately syn.- chronized with the horizontal header table, it does not follow that the fish after being beheaded will necessarily arrive in correct, synchronism at the pickeup point for engagement by the bull rings positioning means. At least two factors have operated to disturb such synchronism at this point. For one, those fish-advancing means by which the fish are individually advanced fiatwise of and disposed transversely upon the header table are not arranged to advance the fish lengthwiseto and then circularly about the path it follows through the fish cleaning machine; the fish must change its direction and its attitude, and must greatly increase its speed of movement in the tailward sense, hence the header table feed means must disengage each fish after it isbeheaded and before it arrives at the pick-up point to be engaged by the bullring. For an interval the fish has heretofore laid in or moved along the trough, freed of positive control, while it changed direction and again moved in another new direc tion and in a changed attitude, and because of dififerences between individual fish, or between the attitude or positioningof'successive fish when thus released and when moving in. the trough. some will move more freely or more accurately than others, and thus synchronization may be destroyed. A second factor is found in the difference-in length of individual fish, and in the relationshipof their varying lengths to theirnniform spacing upon the feed table. Allare accurately aligned-by their pectoral girdle, just be.- hind the head, at the time they pass the beheading point, but almost immediately thereafter must move rapidly tailward'to the pick-up point, and apoint in the vicinity ofthe tail oi? each fish must be rather accurately located in time. for pick-up. It is obvious that a long fish requires less movement tailward from beheading position to pick-up position than does a short fish, and that since the interval permitted for-such movement is necessarily short, being onlythe time required for an eight-inch advance of the header table feed"means, any impositive ornonsynchronized force (gravity, for instance) intended to accomplish such tailward movement will notinfrequently fail to do so in time. The mere pro.- vision of means to positively advance fish along the trough will not necessarily insure the desired synchronism. Inded some fish may be so long as to overlap the bull ring position of a following fish, which, if a second fish must follow at a definite interval, regardless, 'will cause. a jam, and so the provision of ayieldable drive iorsuch fish-advancing means will not alone solve the problem, for if an overlarge fish may cause a stretch-out. of the trough interval, the intended synchronism between header table and bull; is destroyed.

n th past a speed of o er tien Q fi t pi fish a minute was deemed ample nor was ite sidered nqm al t s atien as r a e a the trough, who, y hand wou d m re he fish along the trough into positionv for engagement by thev bull ring as the latter moves upwa, -ly past the fish at the pick-up point, and who would see to it that each fish was correctly pinned upon the bull ring. It has also been attempted to cause th P li 19 a ty 191 5 he trough reenter p ck- 12 osi n' ag b he 3 bull ring, but this did not operate with entire satisfaction, for some fish will slide more readily than others, and some are long and some are short, and the long ones might arrive too soon at the pick-up point, the short ones too late.

With the very greatly increased speed of operation now employed, in the neighborhood of 110 to 120 or 130 fish a minute, and with a speed of 150 fish a minute possible, even were it economically feasible to station an operator at this point, it would be physically impossible for him manually to advance the fish in proper synchronism along the trough to the pick-up point, and the increased speed of operation has made the fish much more diflicult to control and engage properly with the positioning pins of the bull ring. Nevertheless, since the accuracy and thoroughness of cleaning, and freedom from damage or frequent jams, depends upon the accuracy of the fishs engagement with the positioning pins, even more so than before, it has been found necessary to provide mechanical means to effect advance of the fish along the trough into proper position and in correct synchronism for pick-up by the bull ring, to insure that such pick-up is initiated and completed smoothly and accurately, and to provide means which are automatically self-adapting to handle random and widely varying sizes of fish, without destroying the synchronism between the several parts of the machine. I

The provision of means to such ends, operable in correct synchronism with the feed table advancing means and with the bull ring, and selfrestoring after most departures from synchronism, is the primary aim of this invention.

Moreover, by the accomplishment of the general object just indicated, a further important object is accomplished, which is to eliminate the necessity of an operator stationed at each such machine, and to permit a single operator to have general charge of several machines, his principal duty being to insure that all are functioning correctly over-all, or to stop any given machine or clear a jam such as may infrequently develop, and restart the machine.

The accommodation of the feed of fish along the trough, and their positioning in proper synchronism for pick-up by the bull ring, yet by means which is automatically self-adjusting to different sizes of fish, is an important object of the invention. Furthermore, since the fish will vary in size, and some may even be so large as to lap a second or following station upon the bull ring, it is an important associated object to provide such feed means as will effect such automatic compensation for variations by as much as from eight to thirty-two inches in the size of individual fish, or up to the point where one fish overlaps two fish-holding stations, without disturbing the synchonous relationship between the feed means and the bull ring, and which in the event of such disturbance of the synchronous relationship as is occasioned by an oversize fish occupying parts oftwo bull ring stations, will automatically stop the feed, and resume the proper synchonous relationship between the feed means and the bull ring upon resumption of the feed of the next fish under control of the operator.

Moreover, even though a given fish be not so hugely oversize, if it is sufficiently large to disturb the synchonous relationship, it is an object to provide means to restore that relationship automatically immediately such larger fish is delivered to the bull ring, and in that-manner 4 to maintain at all times a. predetermined synchronous relationship which may momentarily yield to accommodate fish differing from a predetermined average or minimum size, but which is self-restoring to handle such predetermined size or any larger size.

Likewise it is an object to provide means whereby the machine may be adjusted if preferred, to accommodate different average or minimum sizes of fish according to the particular run of variety being handled, or to alter the phase relation of its feed relative to the header table feed, or to the bull ring.

Because of the rotation of the bull ring at a rate suificiently rapid to handle in excess of one hundred fish a minute, and the necessity of picking up at a given point in the rotation of the bull ring a fish stationed at such pick-up point, and the practical difliculty on the one hand, of proper engagement with the stationary fish as the bull ring passes at high speed, or on the other hand, of permitting frictional engagement of the fish with the bull ring to initiate circumferential movement of the fish prematurely, it is a further object to provide mechanism whereby the fish is stopped at the proper point in its tailward movement, and thereafter is given a correctly timed movement which has a circumferential or tangential component substantially synchronized with the circumferential movement of the bull ring, so that thetail end of the fish moves with the bull ring from the pick-up point onwardly for a distance sufiicient to enable at least the first positioning pins to engage properly with the fish.

It is an associated object to provide means which will insure that the fish, after such first engagement with the bull ring, will be drawn and held closely against the periphery of the bull ring for correct engagement of the subsequently engageable positioning pins spaced along the back of the fish.

Because of the rapid movement and abrupt change of direction of the fish as it is picked up by the bull ring, there is sometimes a tendency for the fish to whip about, which would displace it from proper position for engagement before it has been fully engaged, and while it is still supported principally in the trough, and it is a further object to provide means to restrain such movement of the fish, while yet accommodating itself to fish of varying size.

Notwithstanding all safeguards, fish may sometimes pile up, jam, or fail to feed properly through the Iron Chink, or through the feed mechanism, and it is a further object to provide, in association with the feed regulating mechanism, throwout means operable automatically or manually, or both, by which the feeding means may be disconnected from the drive mechanism, and yet may be restored to correct operative and synchronous relationship when the jam has been cleared, without thought or adjustment to the end of such synchronization on the part of the operator.

While the run is on, such machines are operated throughout long shifts by operators who may be unskilled, or who may become tired or inattentive, and at locations where mechanical service is not readily available, yet where a breakdown will result in the spoiling of many fish, and in large economic loss. It is another object to provide mechanism of the nature indicated,

15 which is of simple nature and thoroughly rugged S and d enda sq hat u h b k ns a e unik l a d n q e t Man other objects will ap ear s t is ecification progresses; but enough has been said to indicate the general nature and objects of the invention.

The well-known Iron Chink fish dressing.,machine includes a two-part bull ring 9 and 99, mounted for rotation upon supporting rollers 9|, and rotatable by means of driving pinions 92 on shaft 92a engaging bull gears 93, which are fast to the, two. parts ofthe split bull ring. These two parts of the bull ring are joined for conjoint rotation, and carry cooperating. pairs of fisheengaging pins 94 and 95. These pins are controlled by cam followers 96 running. in stationary circumferentially slotted cam rihgs 91 to press the pins together at a pick-up point to pierce" the back of a fish and thus to hold the fish to the bull ring, in anattitude tail foremost and belly outward. The fish are thus carried through a circumferential path, where various actions take" place, such as finning, splitting, and cleaning out of the entrails. The mechanism'for accomplishing these operations has not been shown herein, since it is well-known, and'in itself does not concern this invention. Upon completion of theseveral operations the pins 94 and 95 are withdrawn, and the fish is discharged and carried on, For examples of such fishdressing machines reference is made to patents to Waugh No. 1,542,196, dated June 16, 1925; No. 1,459,273, dated June 19, 1923; No. 1,365,575, dated Jami ary 11, 1921; and No; 1,360,064, dated November 23, 1920. In the arrangement shown in Figure 1 the selective clutch and change-speed drive has been suggested at 98, the nature of which or the possible speed variations whereof are immaterial other than to indicate that the drive for the fish dressing machine, and for other mechanism to be described; is obtained from the shaft 99, through the selective change-speed mechanism at, to the driven shaft 92a, whereon is mounted the bull ring driving pinions 92. The shaft 9|a of the rollers 91 serve as hangers to support the cam rings 9?, through brackets 91a, and the two cam rings are connected by transverse bars 91b.

Supported on a bar 91?), won any other con-'- venient support at the pick-up point, which is represented in Figure 2 by the dot-dash outline of a fish, are two fixedly positioned, spaced-apart fish stops 1. These lie just behind and laterally within the adjacent edges of the two. halves 9 and 90 of the bull ring, and they may be ad'- justed laterally to vary their spacing but they should always be more closely spaced than the two halves of the bull ring, in accordance with the thickness at the tail of the smallest fish being handled. Adjusting bolts 19, which hold the respective fish stops 7 to the bar 911?, permit such adjustment. The purpose of the fish stops '7, of their adjustment, and of the ratchet-like teeth or corrugations H on their inside edges, will appear more fully hereinafter.

Before the fish reaches the pick-up point it passes along a feeder table of known type, where each fish is positively engaged, is disposed transversely of the table with its head directed away from the pick-up point, and with its back leading. As the successive fish, at eight-inch spacings, pass along this feeder table, each one is brought into such alignment that the pectoral girdle of each is precisely in line with the peetoral girdle of all preceding fish, and all their pectoral girdles are aligned with a beheading point. As they reach this beheading point, thus aligned, in their passage along the table, each fish is beheaded, and passes promptly thereafter from the feed table for delivery to the, pick-up point. For details of the feed table, its drive, and the aligning and beheading operations, reference may be had to some of the patents mentioned above, or to such patents as Waugh No. 1,909,643, issued May 16, 1933; or Oates No. 2,346,935, issued April 19, 1944; or to my own copending ap plication Serial No. 782,865, filed October 29, 1947.

In the present drawings the delivery end only of the feed table is indicated, by 'means'of which table the beheaded fish are delivered. back dflwn and belly up, into the trough s. The positively driven lugs 8| projecting above their supporting chains 82 which pass about the powered sprocket 83 (see Figure 3) constitute the means by which the fish are positively advanced along the feed table 80. The sprocket wheels 83 are positively driven, by the usual means, including the bevel gears 94, one of which is on an extension of the shaft 92a, and the other of which is on the shaft 85, in synchronism with the remaining mechanism. For further details see certain of the patents mentioned above.

In the past it has been attempted to effect gravity movement of the fish down the trough 8 toward the pick-up point by inclining the trough downwardly toward the pick-up point. This operated wih only fair success, for some fish are more slippery than others, and the dorsal fin, as it tended to raise or to lie fiat, created more or less resistance. Usually it was necessary to station an operator at this point to move the fish by hand toward the pick-up point as they drop into the trough. With more recently increased speeds of operation even this has not operated satisfactorily, and so the problem has been to insure proper coordination and. synchronism between the fish which must be released by the driving lugs 8| to cause them to arrive at the pick-up point in time to be engaged by the initial positioning pins 94.

As has already been indicated, the problem is more than merely the provision of mechanical means to move the fish down the trough tailward to the pick-up point with suificient rapidity. The problem is complicated by the necessity for handling random sizes of fish, for in any given run some fish will be large and others will be small, as it has been attempted to indicate in Figure l. Machine-cleaned fish range from eight to thirty-two inches in length, after beheading. All such fish have previously been aligned for beheading along the line of their pectoral girdles, as is indicated by the two fish which still rest upon the feed table in Figure 1, but each such fish, whether oversize or undersize or average-size, must be moved tailward through a greater or lesser distance, depending upon its size, in time to arrive at the pick-up point, and there to be stopped by the tail stops 1 of the fish-cleaning machine, and thereafter to be firmly grasped in the vicinity of its tail by the closing of the positioning pins 94 carried by the bull ring halves 9 and 90. The time permitted for such tailward movement is brief, and is identical regardless of the size of the individual fish. If the fish is undersize it must move farther, but still must arrive in time. If it is of average size there must be some adjustment of the position of the feed means as between the under-size and the average-size fish; otherwise there is failure of synchronism in the drive means as between the header table and the fish dressing machine. Still further, if the fish is greatly over-size, it may be so long as to overlap a second station on the bull ring, and there must be provision that such an over-size fish, which greatly disturbs the synchronous relationship between the various parts, will not, by itself or in conjunction with a following fish, create a jam in the fish dressing machine. It is to the solution of such problems that the present invention is particularly directed.

.Each fish, promptly after it drops into the trough 8, is engaged at its neck, whence the head has been severed, by a pusher element I, mounted upon a chain l and projecting through a slot in the side of the trough. This chain,

mounted upon sprocket wheels II and I2, is positively driven in such phase relationship to the delivery of fish into the trough by the lugs 81, and to the arrival at the pick-up point of the fish-piercing positioning pins 94 on the bull ring, that each fish will be engaged along the line of severance just behind the pectoral girdle, and will be advanced so that-its tail arrives at the pick-up point in advance of the arrival there of the pins 94. Usually the device will be adjusted to handle the minimum size of fish, say eight inches in length after beheading, and the timing will be such that the tail of a fish of that minimum size will arrive between and be stopped by the fish stops '1 just before the pins 94 arrive to engage the fish. It is obvious that the tail of a longer fish, being nearer the pick-up point at the beginning of tailward movement, will arrive sooner at the pick-up point, and must wait there until the pins 94 arrive. The pusher element I must halt, in the latter case, until the longer fish moves on, and the mechanism which permits this, and which causes the pusher element to catch up again and to resume its initial phase relationship, will be explained in detail hereinafter. However, as will also appear, the phase relationship is adjustable, if desired, to accommodate fish which are all longer than the minimum length.

The purpose of the lateral adjustment of the tail stops 1 will now be plain. Small fish are not as thick, at their tail, as the large fish, yet the fishs tail should enter between the bull ring halves 9 and to an extent sufficient to engage the pins 94 in the solid flesh, yet not too far forward of the tail. For fish averaging smaller than a run of larger fish, the tail stops 1 would be closely spaced; for larger average fish, they would be separated more widely.

It is quite essential that the fish be stopped in correct position at the pick-up point, and that its tail remain so positioned until the primary positioning pins 94' arrive there. Because the latter are rotating with the bull ring, at a rapid rate, it is highly desirable that the theretofore stopped tail of the fish then move in a generally circumferential direction at a rate which is more or less synchronous with the rotary rate of movement of the pins 94, so that the latter may have time to pin the tail securely while there is no appreciable relative movement between the tail and the pins 94. An abrupt change of direction of the fish, and rapid acceleration of its tail from its momentarily fixed position, are involved. Fish-positioning means are provided at the pick-up point to assist in the attainment of these ends. They may be of either of two forms, or, preferably, both forms are used in conjunction, as will now be explained.

The adjustable fish stops 1 have already been explained. The fishs tail, entering and wedging between the two halves thereof, halts its tailward movement under the influence of the pusher element I. The fixed stops 1 hold the fish from contact with the rotating bull wheel 9, 90, and the teeth ll discourage any tendency which might result from incidental friction between the fish and the bull ring halves, for the fishs tail to rise, until the proper time. At that time, the slope of the teeth 1| permits upward movement of the tail without undue effort or restraint.

A tail snubber 2 serves also to position the fish at the pick-up point, but its principal function is to start the circumferential movement of the 9 fish at the proper time and to accelerate that movement sufficiently rapidly, and to such speed, that the fishs tail is substantially immovable relative to the rapidly rotating positioning pins 94 while the latter are penetrating the fish at or near the tail. Thereafter the tail snubber 2 yields to permit the pinned fish to be drawn upwardly by the bull ring and its positioning pins, and to hold the fish close to the bull ring while the successive sets of pins 95 penetrate its back.

This snubber 2, such as has before been stationarily disposed at this location, consists conveniently of two halves cooperating to form what is in the nature of a funnel. two halves being connected together by the gearing 2B for conjoint opening and closing movement, and being urged toward closed position by resilient means indicated at 2 I. Instead of being stationary, as heretofore, the whole is mounted, preferably for some vertical adjustment, by a bracket 22 upon a vertical slide 23, which is guided at 24 in the frame for vertical movement. A cam follower 25 upon the lower end of the slide 23 is engaged within a rotative channel-like cam 26, to cause abrupt raising of the means 2, and its lowering again, in synchronism with the remainder of the mechanism, and in a manner which will be explained more fully hereinafter. The vertical adjustment permitted at 29 enables close coordination between the snubber 2 and the pins 94.

The fish-positioningmeansat land at 2 serves, then, three functions: First, the means 1 serves to permit the tail to pass through but stops it in pick-up position, with the tail projecting into the split between the halves of the bull ring, by means of the snubbing action as the stops engage the thicker portion of the fish just ahead of the fishs tail; secondly, by its correctly timed upward -movement under the influence of the cam 26 the snubber 2 causes the tail of the fish, so engaged, to rise at the same time and at about the same speed as the circumferential movement of the positioning pins 94, so that these pins are better enabled to engage the fish's tail, which, being so moved, is more or less immovable with respect to theupwardly moving positioning pins; thirdly, by the resilient yielding action and downward return movement of the snubber 2 the remainder of the fish, pulled by thev positioning pins 94, is enabled to pass through the funnel, but by it is held to the bull ring, so that its back lies along and within the channel of the bull ring for proper engagement of the successive groups of positioning pins 95. I

The drive for the pusher elements I, as 'has been indicated, must be automatically yieldable to fish larger than the minimum or the predetermined size for which it is set, yet self-restoring to synchronism; it should be adjustable .to accommodate different minimum orpredetermined sizes of fish, and it should be so arranged as .to stop the mechanism in the event so large a fish is encountered as would be likely to cause a jam or to overlap two fish-receiving stations on the bull ring.

Starting with the shaft 92a, by which the bull ring is driven from the driving shaft 9.9, a shaft 3|] is driven through the clutch means 3i by means of a chain drive 3.2 about a sprocket wheel 32a loose upon but clutched at 3| to the shaft, or by any similar or suitable arrangement. By throwout of the clutch at 8|, which can be accrue-- pushed by thehand lever 33, the rotation'of the shaft eemay be stopped. When thus driven the.

shaft 3!] drives a gear 34, which isiast upon the shaft (see Figure 5), and this in turn drives a gear pair 355a and 35b carried upon the end of an arm 35 which is loose upon and capable of rotation about the shaft 30. The gear 3% drives a gear 36, loose upon the shaft, and this, through a bevel gear pair at 3!, drives an upright shaft 40.

Secured as a part of the arm 35 is a gear 38, the purpose of which will shortly appear, and throwout cam 39, formed upon this gear 38, cooperates with cam follower 39a, upon the arm 33a, linked by a link 33b to the clutch lever 33, so that the clutch 3| may be thrown out either by the hand lever 33 or through the cam 39 acting through the follower 390., the arm 33a, and the link 33b.

The shaft 4|} is the one whereon the driving sprocket wheel .H is mounted, and by which the pusher is moved, but the connection between the shaft and sprocket wheel is indirect, and may be yieldable or nonyielding, as the operator chooses. Considering first the nonyielding con? nection, the sprocket wheel H is clamped .to a disk 4|, loose. upona hub l3 of the sprocket wheel, by means of a clamping bolt '42 projects ing through anarcuate slot |2 in the sprocket wheel and threaded within the disk 4|. A housf ing 43 is held fast to the disk 4| by a boltor'pin 44 passing through lugs 4|a on disk 4| and 43a on housing 43. By means of a pin 45a projecting from a collar 45 for reception in one of several circularly arranged holes 432) in the housing 43, the housing and. collar must rotate together, The collar 45 is keyed to a bushing 46, which is pinned to the shaft 40 by the set screw 46a. Now, since the bushing '46 is fast upon the driving shaft 4|], and in turn 45 is keyed to 45, 43 is pinned to 45, 43 is locked to 4|, and 4| is clamped to II, the sprocket wheel H is nonyieldingly driven from the shaft 40.

The phase relation between the drive shaft 30 and the pusher I may be varied by shifting angularly the sprocket wheel relative to the shaft 4|). Such shifting may be resiliently yielding and momentary, as will shortly be explained, or it may be semi-permanent and nonyielding. In the latter case, bywithdrawing the pin 45a from its hole 43b, then, rotating the sprocket wheel and housing 43 and reengaging pin 45a in a different hole, the phase relationship is changed, but not yieldably. The spring 4'? between the collar 45 and a second collar 48-the latter held to the bushing 43 by a set screw 460- permits such withdrawal of the pin 45a, but retains the latter in any selected hole 431).

Since yielding and resiliently returnable momentary alteration of the phase-relation between the drive shaft 30 and pusher is always desired,

one way of accomplishing this is through the spiral spring 4. One end of this spring is fast to the sprocket wheels hub I3, and its other end is fast to a pin 43c carried by the housing 43. The

spring is initially loaded by a pin 49 projecting from the disk 4| into the path of the pin 43c, to

' limit relaxing movement of this end of the spring. By angularly adjusting the disk 4| and its pin 49 relative to the sprocket wheel H, the spring loading may be varied; this is the reason for the adjustment at the clamping bolt 42 within the arcuate slot |2. Of course, if the pin 44 remains in engagement with both lugs 41a and 43a, the spring 4 is, wholly inactive, regardless of increase ordecrease in its loading, so the pin 44 must be removed before a resiliently yielding phaseshift canoccur at thispoint. 1 lt; can

and ordinarily does occur at a different point, as will now be made clear.

Meshin with the gear 38, previously described, is a gear segment 50, which is mounted upon a rock shaft for oscillation'about the latters axis; see Figure '7. The connection between the gear segment and the shaft 5|, however, is by means of a spiral spring 5, which is so arranged as to tend to hold the gear segment 50 always in a limit position, where, through the gear 38, it urges the arm 35 into a position against a resilient buffer 53. If, however, there is a sufiiciently strong tendency for the arm 35 to move in the direction of the dotted arrow shown in Figure 4, as would occur when a long fish is stopped by the positioning means 2 while the pusher I still urges it along the trough 8, the gear segment 50 is rotated against the force of the spring 5, but upon removal of the force represented by the dotted arrow in Figure 4, as would occur when the halted fish is engaged and pulled upward by the bull ring and its pins 94 and 95, the spring 5 will return parts to their initial position, the arm 35 will again contact the stop or bufier 53, and the pusher previously momentarily halted, will leap ahead until it resumes its original phase relationship. Thus there is no disturbance of that phase relationship, nor of the synchronism between the header table and bull ring respectively.

If the stoppage is sufficiently long continued, as might occur by reason of a greatly over-size fish, rotation of the arm 35 and of the gear 38 will bring the associated earns 39 into operative relationship to the follower 39a in such manner as to move the clutch elements at 3| in a direction to release the clutch, and when this occurs, the operation of the mechanism ceases until parts are manually restored to operative relationship. This action is intended to occur only when a fish so large as to overlap two stations on the bull ring is fed by this feeder mechanism. When the clutch at 3| is reengaged, the disturbing stress having been removed, parts again and without care to that end automatically are restored to proper phase relationship.

The function of the cam 26 has been described heretofore. It is driven by an extension of the shaft 30, through the bevel gear drive at 2'! to the vertical shaft 28, whereon the cam 26 is fast. After disturbance of the phase relationship by yielding at 5, or at 4, or after throw-out by cams 39, resumption of drive through reclutching at 3| to shaft 30 automatically restores the phase relationship to the cam 26, and the latters synchronism to the bull ring, and hence to all other driven parts, is maintained through the same shaft 30. Always, as the pins 94 of each successive station on the bull ring rise past the pick-up point, the tail-positioning means 2 rises also, and allows time for closing of the pins 84 upon the fishs tail.

The high operating speeds and abrupt change of direction at the pick-up point, coupled with the downwardly pressing action of the snubber as it returns to its lower position, or with the tailward pressure of the pusher on a soft. fiabby fish, tend sometimes to fiop the fish out of the trough and out of the snubber 2. A spring-biased arm 6|, pivoted at 60, carries a plate 6 which overlies the trough 8 somewhat behind the snubber 2, and bears down upon each fish. Without impeding its movement, this hold-down device-5 restrains such flopping of the fish, and- 1'2 permits each fish to rise only as it passes through the snubber 2, close to the bull ring.

The operation should now be clear. Each fish, after beheading, is released by the header table feed means 8|, drops into the trough 8, and is promptly and positively shifted tailward until halted by the tail stops 1, assisted by the snubber 2. Its dorsal fin, depending within the channel 86 (see Figure 6) has no tendency to rise and impede the fishs advance. The snubber 2 moves upward, lifting the tail in synchronism with upward movement of the pins 94-, until the latter are firmly engaged with the tail. Such engagement continues upward, tailward movement of the fish, dragging it beneath the hold-down 6 and through the snubber so that the successive pins 95 engage it firmly. Thus is the fish moved in correct synchronism from the header table to the fish cleaning machine, and whenever synchronism is disturbed, it is automatically restored, usually without stoppage of the mechanism, but synchronism is also restored automatically in case stoppage occurs under conditions that otherwise would cause a jam. Phase relations are adjustable. The restoring force can be as soft or as stiff and rapidly acting as desired, by simple adjustments. The entire operation is substantially automatic, and an operator to feed each machine is eliminated, yet the operating speed is increased.
